Is it possible to get SDS bits, think my drill is SDS plus, that will drill into metal; I've had no luck finding them before. My only drill is SDS, and I can't afford to buy another at present. I've had a chuck adapter for a number of years, but it adds a little bit of a wobble to the drill and as I expect to be drilling some 3mm steel soon I might put too much strain on that if I have to use the adapter. Any suggestions? Thanks all.
